Fig. 6From: Out-of-the tropics or trans-tropical dispersal? The origins of the disjunct distribution of the gooseneck barnacle Pollicipes elegans Representation of the demographic models simulated with BSSC followed by Approximate Bayesian Computation to evaluate the plausibility of vicariance and dispersal as the origin of parantitropical distribution of Pollicipes elegans. T0–1 time of splitting event; Anc0–1 Ancestral Ne at the moment of splitting; Bot 0–1 bottleneck events before splitting events. Panel a and b represent vicariance demographic models with a tropical origin. Panel c and d represent stepping stone dispersal demographic modelsBack to article page
